Statistical Models in RUniversity of Notre Dame

Statistical Models Measures of Fit Quality A quantity frequently reported in a model is R2 Given the y values y 1 y n the mean of y y and the tted values y 1 y n R2 = P n i=1 y i y 2 P n i=1 y i y 2 This is a number between 0 and 1 The quality of t increases with R2 The adjusted R2 does some adjustment for degrees of freedom
